Oil Paint
Dear Mitra experts, how much wax can be added to a blob of paint until it turns the paint solvent sensitive once dried?
And dammar?
Thank you in advance!

With soft resins, the problem is that they start to become
problematic in about the percentages where you start to notice an effect. It is
best to just avoid them as paint additives.
You can get away with wax a bit more but only because it
starts to really change the handling at very low concentrations. The old rule
of thumb was 2% by weight but that is probably erroneous. 2% be weight of wax
in a very light pigment would actually correspond to a rather large proportion
by volume. I personally do not like what wax does to oil paint and do not like most
paints “stabilized” by waxes and aluminum stearate. They tend to make a rather homogeneous
product that handles uniformly, but in a boring manner for me. As is stated on forums
about other subject that I subscribe to, “your mileage may vary” meaning that we
all have different needs and expectations.
